IMPROVEMENT IN PAPER-COLLAR MACHINES.

Specification forming part of Letters Patent No. 209,628, dated November5,1878; application filed J one 27, 1878.

To all whom it may concern:

Be it known that I, CHARLES Srorronn, of the city, county, and State ofNew York, am the inventor of certain Improvements in Machines for MakingPaper Collars, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My invention relates to a machine for makin g paper collars, in whichthe collars are stamped and out from strips of paper by dies providedwith reciprocating plun gers; and my invention consists in thecombination, with the collar forming dies, of the rotary cutters,hereinafter described and shown, whereby the strips from which thecollars are formed by the dies are out from sheets of paper employedconjointly with the forming of the collars by the dies, the cuttersbeing actuated by the same motivegear which drives the other parts ofthe machine, as hereinafter described; and my invention also consists inthe peculiar arrangement of the dies, in their relation to each other,whereby at the same time that a collaris stamped by one die, and the.collar just previously stamped by said die is cut out by another die,longitudinally adjacent to said first-named die, on one edge of a stripof a width equal to the sum of the greatest and least width of thecollars produced. A collar is stamped by a third die upon the other edgeof the strip, and laterally adjacent to the cut made by saidsecond-named die in forming the collars upon the opposite edge of thestrip, as hereinafter particularly set forth.

And my invention further consists in the feed-rollers, hereinafterdescribed, in combination with the rotary cutters, and arranged tooperate as specified.

Figure l is a front elevation of a paper-collar machine embodying myinvention. Fig. 2 is an end elevation of the same. Fig. 3 is a rearelevation of the same, showing the drivinggears. Fi 4 is a plan of thesame. Fig. 5 is a view in detail of the loose pinion, with its ratchetand pawl and its engaging rack, which I employ to communicate from thedrivinggears to the feed-rollers and rotary cutters the desiredintermittent rotary motion; and

Fig. 6 is a plan of the sheet of paper fed to my machine, showing themanner in which the collars are formed thereon by the dies, arranged asdescribed.

A, A and A are dies, provided with suitable plungers, and mounted on aframe or table, as shown. The plungers are given a verticalreciprocating motion in their dies by means of the rods 0-,eccentrically connected with the shafts a which are driven by the gears(L as shown.

At B are shown the feed-rollers. These are arranged one above and onebelow the table, and their rims meet in a slot in the table on the lineof the top thereof. The rollers are mounted on the shafts b, and aregiven an intermittent rotary motion from the gears a? by means of therack b on the rod I)", which is operated by one of the gears, a, asshown, engaging the loose pinion h, on one of the shafts, I), the saidpinion having a ratchet, with which engages a spring-pawl on a hubpiecefixed on the shaft. The movement ofthe rack on the pinion will, by thisarrangeother. By this means the cutters O are given the rotary motionnecessary to accomplish the cutting of the strip from which the collarsare formed from the paper sheet.

It is obvious, however, that the cutters may be mounted on shafts oftheir own, and driven by gearing suitably connected with the motive gearof the machine. The cutters should be arranged and adjusted in theirrelation to the dies, so as to cut from the sheet fed to the machineastrip equal in width to the sum of the greatest and least width of thecollars to be produced. I

The feed-rollers are placed at that end of the table of the machinetoward which the paper strip travels in being fed to the machine andbeyond all of the dies, and hence the paper is drawn along the tablethrough the machine, and thus fed to the dies successively, and therebythe crumpling ot the paper on the table, and consequent waste, whichoccurs when the paper is pushed along the table in feeding the dies, iswholly avoided.

It is evident that by means of my rotary cutters the strip from whichthe collars are formed will be out from the sheet of paper fed to themachine conjointly with the forming of the collars by the dies, therotary cutters being actuated by the same motive-gearing, a, as thedies, and that hence the cutting of the paper sheets into strips beforebeing fed to the machine by a separate and distinct operation isavoided, and the paper employed may be used and fed to the machine inthe wide-sheet form in which it is usually manufactured.

"""The dies in my machine are arran as follows: The die A is placed atone end of the table, as shown, and stamps the collar (seen at D, Fig.6) upon one edge of the paper strip formed by the rotary cutters fromthe sheet fed to the machine. The die A is placed longitudinallyadjacent to the die A, and cuts out the collar stamped by the die A, asseen at D, Fig. 6.

The collars cut by the die A fall through said die, and are thus carriedout of the machine, an opening in the table of the machine, below saiddie, and extending through said die, being provided for this purpose.

The die A is arranged to stamp a collar upon the opposite edge of thestrip formed from the sheet by the rotary cutters, and the said diebeing placed, as shown, at a distance from the die A equal to one-halfthe length of a collar formed by the dies, the collar stamped by saiddie A, laterally adjacent to the cut made by the die A, has one edgethereof formed by the said out of the die A, as seen at D, Fig. 6.

The other edge of the collar, stamped by the die A is formed or cut bythe rotary cutters, which, as hereinbefore specified, are arranged andadjusted to cut the strip from which the collars are formed equal inwidth to the sum of the greatest and least width of the collars formedthereon by the machine.

The collars stamped by the die A are severed from the strip in whichthey are formed by the cross-cutting shears E, which are placed on thetable of the machine at a distance from the die A equal to the length ofa collar.

The shears E are arranged at right angles to the paper strip, and oneblade is given a vertical vibrating motion by the rod 6, fixed on theplunger of said die A, and engaging the end of said blade, to accomplishthe severing of the collars D from the strip.

When the machine is in operation it is evident that at each movement ofthe plungers of the dies A A A a collar will be stamped by the die A,and the collar stamped immediately before by said die will be cut by thedie A on one edge of the strip formed by the cutters 0 from the sheet,said collar thus formed being dropped through the die A, and through theopening in the table below said die, and thus out of the machine, and acollar will be stamped by the die A upon the opposite edge of saidstrip, laterally adjacent.

to the cut made by the die A, and said out constituting one edge of saidcollar, while the shears E will sever from the strip the collar stampedimmediately before by the die A; and that the cut made by the die A ismade to constitute one edge of the collar stamped by the die A by theplacing of said die A at a distance from the die A equal to one-half thelength of a collar formed by the dies.

It is obvious that the dies, arranged as specified, will perform theirfunctions, forming the collars, as described, when the rotary cutters Gare dispensed with, the paper sheet employed being cut into strips ofproper width by a separate operation before being fed to the machine.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a machine for making paper collars, the combination of thecollar-forming dies with the rotary cutters G, actuated by themotive-gearin g of the machine, and arranged to cut the strip from whichthe collars are formed from the sheet employed conjointly with theforming of the collars, as described.

2. In a machine for making paper collars, the dies A and A,longitudinally adjacent to each other, and arranged to form a collar onone edge of a paper strip of a width equal to the sum of the greatestand least width of the collar produced, and the die A placed at thedistance of one-half a collar from the die A, to stamp a collar upon theopposite edge of the strip, as and for the purpose specified.

3. In a machine for making paper collars, the intermittently-rotatingfeed-rollers 13, carrying the cutters 0, arranged on the table of themachine on the end toward whichthe paper travels when fed, whereby thepaper, in

feeding the machine, is drawn along the table by said rollers to thedies successively, and the strip from which the collars are formed iscut therefrom, as and for the purpose specified.
